Universal’s been saying for a while now that the entire American Pie gang would be returning for American Reunion, and what do you know, they’re actually making good on that promise. Thomas Ian Nichols has just signed on for the fourth theatrical entry of the long-running American Pie franchise, making him the last major character to sign on. Fellow Pie stars Alyson Hannigan, Seann William Scott, Jason Biggs, Tara Reid, Mena Suvari, Chris Klein, Eddie Kaye Thomas and Eugene Levy have all previously confirmed their involvement.

I haven’t heard any news on whether Jennifer Coolidge might be reprising her role as the original MILF, but as The Hollywood Reporter calls Nichols the “last holdout,” I’m guessing that’s a no. We’ll miss you, Stifler’s Mom!

In the 1999 film, Nichols’ Kevin Myers was one of the four central friends who made a pact to lose their virginity before graduation. The new sequel will see the original gang returning to their hometown for their ten-year high school reunion. American Reunion will hit theaters April 6, 2012. [The Hollywood Reporter]
